CPU getting stuck in flush_tlb_others_ipi

SUSE Linux Enterprise Server 11 Service Pack 1


Customer description "CPU's will go to the max and the server will become unresponsive"

We used an NMI to force a kernel core.
On the stuck thread you would see "flush_tlb_others_ipi" near the top of the stack.


This is fixed in SLES 11 SP2.
